The OCZ Summit: First with Samsung’s New Controller
Well before Intel ever introduced the X25-M, there was one chip company who had already been making well behaved SSD controllers: Samsung.
The fit just made sense; Samsung makes NAND flash, Samsung makes microprocessors, thus Samsung should make SSDs.
Samsung is a unique company in that it is very well known in both the OEM and consumer spaces. You’ll find Samsung ICs in nearly everything; DRAM, smartphones, even the flash on the JMicron drives I’m always complaining about - Samsung makes it. With strong OEM ties as well as a good-sized HDD business, it didn’t take long for Samsung to get into the SSD market.
Because it was primarily selling SSDs to OEMs like Apple and Dell, the controller had to be perfect. Stuttering, pausing and strange reliability problems wouldn’t cut it. Apple wouldn’t dare ship a MacBook Air with a SSD that would deliver anything less than a flawless usage experience.
With that sort of pressure, Samsung’s SSDs and its controllers always just worked. Even before the JMF602A ever shipped, Samsung’s controllers were doing just fine. They had to. Their customers were Apple and Lenovo, there’s no room for silliness.
There were two problems with Samsung’s controllers: 1) they were expensive, and 2) they weren’t very fast.
The cost drove SSD makers to companies like JMicron, to drive SSD prices down faster than Samsung would allow. The performance made it so that the very first SSDs weren’t much faster than the fastest hard drives, and in some cases they were slower.
Late last year Samsung announced a new version of its MLC controller that would slowly replace all of the existing Samsung MLC drives in the market. OCZ was the first to get us a sample based on this new controller, even faster than Samsung and the drive is called the Summit.
OCZ's Summit, it's an early sample
Lots of glue and no screws on the pre-release Summit. The final drive should be ready soon.
I’ll save a detailed investigation into the Summit and Samsung’s controller for another article, this one is already long enough. The Summit should be priced similarly to the Intel drive, although OCZ is trying to make it cheaper. The performance level is designed to be greater than the Vertex and competitive with the Intel X25-M. We’ll see about that shortly.

Also created an account just to post this comment.Really impressive and well done article ! Will stay tune for further developments and reviews. Thank you so much :)
Also... very impressed by OCZ's respond and commitment upon end users needs and product quality assurance (unfortunately not so commun by large this days among other companies). Certanly will buy from them my next SSDs to reward and support their healty policy.
Be well ! ;)

This truly was a GREAT article. I enjoyed reading it and was very informative. Thank you so much. That's why Anandtech is the best site out there.davidlants - Friday, March 20, 2009 - link
This is one of the best tech articles I have ever read, I created an account just to post this comment. I've been a fan of Anandtech for years and articles like this (and the RV700 article from a while back) show the truly unique perspective and access that Anand has that simply no other tech site can match. GREAT WORK!!!Zak - Friday, March 20, 2009 - link
I just got the Apex. I'd probably cough up more dough for the Vertex after reading this. However, I've run it for two days as my system disk in MacPro and haven't noticed any issues, it's really fast. But I guess I'll get Vertex for my Windows 7 build.Z.

What I find intriguing about this article is that these smaller manufacturers do not do real world internal testing for these things. They should not need 3rd parties like you to figure this shit out for them. Maybe now OCZ will learn what they need to do for the future.JonasR - Friday, March 20, 2009 - link
Thanks for an excellent article. I have one question does anyone know which controller is beeing used in the new Patriot 256GB V.3 SSD?

Anyone know if the Vertex Anand used had 32M or 64M cache?Dennis Travis - Friday, March 20, 2009 - link
Excellent and informative article as always Anand. Thanks so much for posting the truth!!IsLNdbOi - Friday, March 20, 2009 - link
Can't remember what page it was, but you showed some charts on the performance of SSDs at their lowest possible performance levels.At their lowest possible performance levels are they still faster than the 300GB Raptor?

It's too bad Windows and applications don't let you select where all the data that needs to be updated and saved to is stored. If that was an option a SSD could be used to only load data (EXE files and support files) and a HDD could be used to store files that are updated frequently, like a web browser for example, their constantly caching files, from the sound of this article that would kill the performance of a SSD in no time.Great article, I'll stick to HDDs for now.
